The mirror has a good range of vision, you can see the entire road and is very helpful on turns. The mirror does not stay pointed very well on rough roads, it vibrates and moves to the outside. It is easy to re-point even while riding.

When riding on narrow roads with average traffic, this mirror is essential so you can see what is coming from behind. The mirror is well made, is easy to install and has an excellent field of view. The only slight drawback is that the setting/orientation of the mirror can change when going over VERY rough roads; but it is easy to readjust.

I am blind in my left eye making it very difficult to look over my shoulder to see traffic behind me. This mirror was just what I needed to feel safe out on the road. The large viewing area lets you see what is coming up behind even with the slight vibration from rough roads. I have had one for years and loved it but recently dropped my bike and broke the support arm. I am buying another now.

Fits great in many places on my STI hoods and drop handlebars. Large viewing area and easily adjustable.

Dealbreaker! Mirror will not stay in position the joint is too loose and even on smooth pavement will vibrate out of position and you look down and see the sky or the back of the mirror instead of the road behind you. Pretty much worthless.
